I have installed an infrared emitter with the following tutorial:

https://www.instructables.com/id/Zero-to-Air-Conditioner-Controller-With-Raspberry-/

But I had trouble running the LIRC commands, so with the help of the pigpio library and this script in Python:

IR Record and Playback http://abyz.me.uk/rpi/pigpio/examples.html#Python_irrp_py

I had managed to set up my air conditioning.

After backing up and reinstalling the operating system (Raspbian Buster on RP3+B) I was not able to get my air conditioning to work.

I don't know if the problem is something electrical or something at the software level. I have controlled with a camera that the emitter emits when it executed the commands. I have in turn controlled the status of the pidgpio service and it returns this to me:

sudo systemctl status pigpiod

Any help?

Thanks!
